OIL-TUBE FOR GAS-ENGINES.

Specification of Letters Patent.

Patented Fence. 1920.

Application filed January 31. 1919. Serial No. 274,321.

of Minnesota, have invented certain new and" useful Improvements in Oil-Tubes for Gas- Engines, of which the following is aspecification, reference being had therein to the accompanying drawing.

This invention relates to oil feeding devices for internal combustion engines and has special reference to means for preventing the clogging of the oil-conducting pipe which conveys oil from the rear of the enine to the forward endthereof as found in the Ford type of engines or others of similar design.

The object is to separate all foreign matter such as fiber from the clutch bands, et cetera. from the oil before the latter enters the tube.

In the accompanying drawings forming part of this application and in which like arts:

Figure 1 is an outline elevation of an engine employing an oil-conducting pipe, with a portion of the side of the engine shown as broken away.

Fig. 2 is an end elevation shown somewhat in perspective of the receiving end, or. funnel, of the oil-conducting pipe,

Fig. 3 is a vertical central sectional view on the line 3-3, Fig. 2.

Fig. 4; is a perspective view of a fragmental portion of a modified form of cover for the receiving end of the 011 pipe.

1 represents the forwardly inclined plpe or tube which is mounted within the crank case of the engine 2, the upper end 3 of the pipe having a flaring or somewhat bellshaped termination or funnel 4 for the convenient reception of oil as it is thrown by centrifugal force from the revolving member 5 of the engine adjacent which it is mounted.

In. the Ford engine, which is the type here shown, the fly-wheel carries the electric current generating magnets and, as it rotates, carries the lubricating oil about with it and it is adjacent the circumferential edge of'the fly-wheel that the mouth or funnel of the tube is laced.

In this manner the oil is caught in the funnel of the pipe as it is thrown from the wheel, and carried through the-pipe to the forward end of the crank pit from whence it works backward and eventually into the flywheel pit again. which results in a continuous circulation of the oil from one end of the engine to the other, while in operation.

The bell-shaped end or tunnel of the pipe is elongated'in a direction transverse the axis of the fly-wheel and the upper face isinclined away from the wheel, there being a considerably lower edge termination at the end of the funnel farthest from the wheel.

Covering the open mouth of the funnel and spaced downwardly from the extreme upper edge of the side walls thereof, are fixed two series of spaced wires 6 and 7, these wires being disposed longitudinally the mouth of the funnel and entirely free at their lower ends, which preferably project considerably beyond the end of the funnel. These wires are fixed within the end of the funnel adjacent the wheel; are spaced apart horizontally and the two series spaced apart vertically, the wires in one series occurring opposite the spaces in the other series, or staggered. as clearly seen in Fig. 2.

The grating thus formed is for the purpose of preventing as much'as possible all solids or fibrous matter from entering the oil'pipe or tube and at the same time restricting the flow of oil as little as possible.

It is obvious from the above that any fibrous substance, such as that which results from the wearing away of the clutch and brake-bands of the engine. when striking the inclined surface presented by the series of wires, will tend to slide along down the wires and fall from the ends thereof instead of entering the tube below.

It is also evident that this will but slightly interfere with the natural flow of oil into the tube and provide simple and positive assurance against tlie latter being clogged up by such foreign material.

In the modified form of strainer, shown in Fig. 4. I have simply roofed the funnel over with a peaked perforated cover 8 so that the oil may freely pass through the perforations into the funnel while the foreign substance will slide off the inclined roof.

Having thus described my invention, what I claim and desire to secure 'by Letters Patcut, is: V

The combination with a rotary oil-dis charging 'member of the character described having a receiving tube adjacent thereto, of

a'strainer for said tube, inclined away from In testimony whereof I hereunto afiiz; my the rotary member and comprising a plusignature in the presence of two witnesses.

rality of s aced wires fixed to that portion n of the en of the tube nearest the rotary CLARENCE member, whereby foreign substance in the Witnesses:

oil will be separated therefrom and washed C. M. OUELLETTE,

off from the lower ends of the wires. S. GEO. STEVENS.
